SPECIFICATION forming part of Letters Patent No. 496,480, dated May 2,1893.

Application filed August 3, 1892- Serial 110.442,.395. (No model.)

,To all whom it may concern.-

Be it known that we, HERBERT E. HAM- ILTON, NAPOLEON BOISVERT, andGEORGE OHAMPOUX, of Salmon Falls, county of Strafford, State of NewHampshire, have invented an Improvement in Looms, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

Our invention relates to improvements in looms, and has for its objectto prevent the shuttle acted upon by the picker-stick, from flying offthe raceway of the lay as the shuttle is thrown from one to the othershuttlebox.

Numerous devices of more or less complicated construction have beenemployed to prevent the shuttle from flying out of the loom. Thistrouble results, we consider, primarily from the imperfect manner inwhich the shuttle is impelled by the picker stick. We seek to overcomethis objectionable feature by so directing the blow of the picker whichimpels the shuttle, that the shuttle will have a tendency to followclosely against or hug the face of the reed, and we have effected ourpurpose by inclining the slots or guides near the bottom of theshuttle-box of the lay in which the picker-sticks Work so that the saidpicker-sticks impelling the shuttle will also be moved forward towardthe front of the lay, a picker and picker-stick having such movementserving to deliver a blow against the shuttle which will propel theshuttle across the lay in such manner that its leading end has atendency to keep close to the reed, and as a result thereof, the shuttleruns practically parallel with the reed and has no tendency to fly offthe lay, and the warps are not injured.

Figure 1, in perspective shows a portion of one end of a lay andshuttle-box and Fig.- 2, is a top or plan view, but on a smaller scale,of a lay provided with diagonal slots in accordance with our invention.

Referring to the drawings, A represents a lay-beam; B one of its swords;O, O, pickersticks, all of ordinary construction. The lay has at eachend a suitable shuttle-box provided, as shown in Fig. 1,.with a suitablebinder a to bear against the shuttle, the binder being acted upon andkept in its operative which the picker-sticks work, the said slots beinginclined with relation to the reed, the inner ends of the slots beingfarther from a vertical plane coinciding with the face of the reed thanthe outer ends of the slots. Ordinarily these slots are parallel withthe reed and with the front sides of the lay-beam. In our invention theinner ends of the slots may be located at the center of the width of thelay-beam, or at one side thereof, as may be found most desirable. As thepicker-sticks are moved forward in the slots f by the usual means, thesaid sticks will be caused to move toward the front part of the lay,such inclined movement of the picker stick causing the picker to bearagainst the end of the shuttle at an angle to its longitudinal center,and as the picker-stick continues to complete its driving stroke thepressure exerted by it against the shuttle will be such as to give tothe shuttle in its passage across the lay a tendency to hug the reedinstead of to fly away from the reed. We have found that the movement ofthe inclined slot to control the picker-stick and thus modify thedirection of its blow, results in insuring a straight move ment to theshuttle without tendency to fly off the race, and the warp threads arenot chafed or broken.

The extent of inclination of the guides or slots and the details of ourimprovements may be varied as found desirable, but the principal objectis to make the picker bear against the end of the shuttle and moveforward at an angle thereto so that it will tend to turn the leadingpoint of the shuttle toward the reed and thus cause the shuttle to runmore 5 nearly parallel to the reed.

Having described our invention, what we claim, and desire to secure byLetters Patent, 18*

In alo01n,a1ay having inclined or diagonal 10 slots or guides in theshuttle box end thereof, combined with a picker-stick adapted to bereciprocated in said guides, as and for the purposes set forth.

In testimony whereof We have signed our names to this specification inthe presence of r 5 two subscribing witnesses.
